They both agree that the catcher is not doing his/her job if he/she allows a base runner to steal the pitch signs. Stealing signs is not unsportsmanlike conduct. It is just part of the game. It is equally not unsportsmanlike if the defense can decipher the base coaches’ signals to the batter and base runners. It is just part of the game.

Either I didn't make my position clear or you misunderstood - I don't think it's unsporting either.
